Earth Overshoot Day

By Earth Overshoot Day 2019, we will have used more from nature
than our planet can renew in the whole year

When will Earth Overshoot Day land in 2019?  Join our contest to guess the date!

Are you a student? A teacher? Middle-school, high-school or university? Tell your class about this opportunity to learn about the Ecological Footprint, to explore data from the National Footprint Accounts, and to study the long-term trend of the global ecological deficit. We created a lesson plan to help guide you through this activity.

Your contest entry is your estimate of the date for Earth Overshoot Day 2019, together with the method you devised to get your result. The winner(s) will be featured on and Global Footprint Network’s social media!

The deadline to submit your guess is May 22, the International Day for Biological Diversity! The date of Earth Overshoot Day 2019 and the winner(s) of the Guess-the-Date Contest will be announced on June 5, World Environment Day.

Explore Solutions

Thriving lives within the means of our planet are not out of reach. Plenty of solutions exist in four major areas
for improving sustainability: food, cities, population, and energy to #MoveTheDate.


city block

Eighty percent of the world population is expected to live in cities by 2050. Consequently, city planning and urban development strategies are instrumental to balancing the supply of natural capital and population’s demand. Learn More



Decarbonizing the economy is our best possible chance to address climate change, and would improve the balance between our Ecological Footprint and the planet’s renewable natural resources. Learn More



How we meet one of our most basic needs–food–is a powerful way to influence sustainability. Sourcing food locally and avoiding highly processed foods can lower the Ecological Footprint. Learn More



Being committed to everyone living secure lives in a world of finite resources requires addressing population growth. Empowering women is essential for global sustainability. Learn More

Support Earth Overshoot Day

We know it can be overwhelming to think about how your personal Footprint contributes to global overshoot. The truth is, you can take steps to chip away at your impact on the planet. If everyone committed to #MoveTheDate 5 days each year, we could get out of global overshoot by 2050.
